Description Frederic Crozat 2009-02-23 07:39:32 UTC
This is a follow-up of gtk+ bug http://bugzilla.gnome.org/show_bug.cgi?id=572387 :

when using non randr 1.2 compatible video driver (old i810 for instance), calling XRRGetScreenResourcesCurrent or XRRGetScreenResources returns no monitor unless XRRGetScreenSizeRange is called before (you won't notice if you use xrandr to query randr info, because it calls XRRGetScreenSizeRange first).

This is with X server and doesn't happen with xrandr 1.2 compatible drivers.
